With the release of Vijay Antony's action thriller Maargan set for a release on June 27, the makers have dropped the trailer glimpse.

The trailer opens with the killer using a substance that blackens people before they die. The killer, played by Ajay Dhishan, displays several physical and mental anomalies during his probe like drinking 20 litres of water at a stretch. It looks like the cop character Vijay Antony plays is also affected by the substance. What is the nature of these crimes, and what bottlenecks arise in the investigation will only be known when the film is released.

The film marks the directorial debut of editor Leo John Paul, who is known for his work in the first two Pizza films, Attakathi, Soodhu Kavvum, Mundasupatti, Thegidi, and Indru Nettru Naalai. He won the Tamil Nadu State Film Award for Best Editor for Idharkuthane Aasaipattai Balakumara, starring Vijay Sethupathi. Leo himself serves as the editor for the film and Vijay Antony is its music composer. The rest of the technical crew comprises cinematographer Yuva S and art director Raja A.

Maargan's cast also includes Samuthirakani, Mahanathi Shankar, Prithika, Brigida Saga, Vinodh Sagar, Deepshikha, Archana, Kanimozhi, and Anthagaram Natarajan.

Releasing in Tamil, the film is also expected to be screened in Malayalam, Kannada, Hindi, and Telugu. Maargan is produced by Vijay Antony Film Corporation.
